Ed is the defrost sensor code on older Marvel units, single and dual zone. Marvel treats it more seriously than the zone sensor codes: a unit that cannot defrost builds heavy frost, and the melt can reach the floor. Marvel says to unplug the unit immediately and have the sensor replaced. Marvel wine cooler display What to do when Ed shows on the wine cooler ### Kind of code Temperature sensors The control has lost a believable reading from one of its thermistors: the probe in a zone, the one on the cold plate or coil, or on some models the one watching the room. With no trustworthy number, the cabinet either chills the bottles far below cellar temperature or lets a zone drift warm. A sensor sitting in frost, pinched behind a rack or unplugged during a move is ruled out before a new one is ordered. ### Usually leads to Wine cooler thermostat and sensor repair Testing and replacing the thermostat or the temperature sensors that tell a wine cooler when to cool, when the cabinet runs too cold, too warm or back and forth. ### Shows up as Wine Cooler Error Code A wine cooler error code appears as letters and digits on the display, a flashing temperature, dashes where a number should be or a blinking symbol, sometimes with an alarm tone and sometimes while the cabinet stays perfectly cool. ### Make Marvel Marvel wine coolers serviced where they are installed, from a warm cabinet to a door that no longer closes tight. ### Source Marvel owner’s guide 41013316 (ML24WB dual-zone wine and beverage unit and related models) Older Marvel units covered by owner’s guide 41013316, which include the ML24WB dual-zone model whose upper zone is meant only for wine.

Unplug the unit, as Marvel directs; if water is already near the outlet, switch off the breaker from a dry spot first. If it comes back, it needs a visit. ### Why does Marvel say to unplug the unit for Ed? Because a unit that does not defrost can build frost that later melts onto the floor. Unplugging stops the cycle until the sensor is replaced. ### What do I do with the wine after unplugging? Move it somewhere cool and dark, away from heat and sunlight. A day or two out of the unit does little harm. ### Is Ed shown on current Marvel wine models? Marvel lists it in the older keypad-model guide. Current models show HH, LL and dr on the display instead. --- **[Read on the site: Marvel Ed: the defrost sensor has failed](https://winecoolerrepair.center/error-codes/marvel-ed/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
